Please ask me to be the emperor

After Zhang Shun earnestly asked for advice, Qintian Supervisor Zhengge Chengke explained everything, and his understanding of the traditional Chinese calendar suddenly reached a deeper level.

After three days of this, Zhang Shun basically "pursued" Ge Chengke's astronomical knowledge, and then he recruited "civilian scientist" Wei Wenkui.

At first, Wei Wenkui was quite decent, showing his solid foundation in the field of traditional astronomy.

However, not long after the contact, this guy turned into a demon. In addition to being extremely disgusted with Western methods, he kept talking about "Zhouyi Bagua, Qimen Dunjia" and so on, which made Zhang Shun confused.

Enduring his headache, Zhang Shun listened for a long time before finally reacting.

It turns out that astronomy is his side job, but his main job is "exploring the avenue of heaven and earth". To put it more bluntly, it is an attempt to fit a mathematical model and calculate all the laws of the movement of heaven and earth and the changes in human disasters.

However, according to Zhang Shun, this is really a lofty ideal, but the reality is cruel.

Not to mention that in this era, even in later generations with extremely advanced supercomputer technology, this is an impossible task.

Of course, just because this guy is so awesome, we can't deny his level.

Of course, you can't live without being crazy. Although Wei Wenkui has some obstacles, Zhang Shun thinks that his calculation ability is even better than that of Ge Chengke.

It's no wonder that he was able to carry the entire Eastern Bureau with his own strength. He fought back and forth with the talented Qintianjian and Western Bureau, and even had a slight upper hand.

Seeing that what Zhang Shun had learned was almost the same as Ge Chengke's, he originally planned to send him back after he finished speaking today.

Unexpectedly, I heard him say at this moment: "...The sun is the king; the five stars are the ministers, so they obey orders like this..."

"Wait, wait, you said, 'The sun is the king; the five stars are the ministers'?" Zhang Shun was surprised when he heard this and asked quickly.

"Exactly!" Wei Wenkui quickly explained.

"The five stars only move in and out of the zodiac within seven or eight degrees. It can be seen that the five stars obey the orders of the sun."

"The longitude, slowness, and reverse of the five stars follow the distance of the sun, and the latitudes of the five stars also follow the distance of the sun!"

"Ecliptic?" After hearing Wei Wenkui's words, Zhang Shun suddenly felt a panic in his heart.

Why?

It turns out that this ecliptic refers to the path that the sun "travels" as viewed from the earth.

Wei Wenkui said that the orbits of the five elements of metal, wood, water, fire, and earth deviate from the ecliptic by only seven or eight degrees at most.

Moreover, the speed, forward and reverse rotation, and distance changes of these five stars in longitude are consistent with the sun.

The appearance, setting and distance changes in latitude are also consistent with the sun.

So these five stars are all rotating around the sun.

This is not heliocentric theory, what is it!

This guy has something! Zhang Shun couldn't help but ask again, "What about the moon?"

"The moon's twilight and twilight angles depend on the distance of the sun. As for the repeated yellow and red phases, the distance between the ecliptic and the ecliptic is six degrees, and there is no disorder. The change of latitude also follows the north and south of the sun." Wei Wenkui laughed when he heard this.

"But the sun is the king, and after the moon appears, its slow and slow movements will be autocratic, unlike the five stars that obey the orders of the sun."

When Zhang Shunyu listened to Wei Wenkui's words, he finally confirmed that this was the so-called "heliocentric theory".

It turns out that he said that although the moon follows the changes of the sun like the five stars of metal, wood, water, fire, earth, the sun is the king and the five stars are ministers, while the moon is the queen and does not completely revolve around the sun like the five stars.

"Is this the result of your research?" Zhang Shun couldn't help but be surprised.

"Your Majesty is joking. Someone has already said this. Common people are just picking on others' wisdom!" Wei Wenkui said with a smile.

"Oh? I see you hate Westerners so much, how did you secretly learn this kind of knowledge?" Zhang Shun felt dark when he heard this, and thought to himself: It turns out that you, with thick eyebrows and big eyes, are also very knowledgeable!

"Xifa? Where did your Majesty start with these words?" Unexpectedly, Wei Wenkui was shocked when he heard this.

"This theory comes from Zhou Shuxue's "The Great Compilation of Shinto and Li Zongyi" written by Zhou Shuxue during the Wanli period. What does it have to do with Western methods?"

During the Wanli period? After hearing Wei Wenkui's words, Zhang Shun suddenly became suspicious of some "conclusive conclusions" in history.

However, Zhang Shun didn't know how many years had passed between this discovery and Copernicus's publication of "On the Revolution of Celestial Bodies".

However, from Wei Wenkui's narration, Zhang Shun discovered that Zhou Shuxue had clearly proved the fact that the five stars of metal, wood, water, fire, and earth revolve around the sun in just a few sentences.

As for the moon, although he did not explicitly mention it, it revolves around the earth.

But according to traditional astronomical knowledge, it also defaults to the fact that the moon revolves around the earth.

No wonder, no wonder your calculations are so accurate!

It turned out that Zhang Shun had seen in previous files that Wei Wenkui's calculation of the solar eclipse in the seventh year of Chongzhen had a large error in the "eclipse amount" item, but in the "eclipse fraction" item, the calculation was almost accurate, which is extremely surprising.

It seems that this person is not only good at arithmetic, but also masters the advanced "heliocentric theory".

Afterwards, the two discussed some "calendar principles". Wei Wenkui mentioned to Zhang Shun that Xing Yunlu believed a little later: "The sun is the ancestor of all things, occupying the position of the king and father, and has the power of development and convergence. The stars and the moon use it to Light, the stars and the stars announce their energy. Therefore, all the numbers are attributed to the sun, and the movement of the stars and the moon are all tied to the same energy of the sun."

This sentence "all are connected by the sun's energy" goes a step further and basically discovers the gravitational effect between planets.

After Wei Wenkui's narration, Zhang Shun couldn't help but look at him with admiration. At the same time, he also realized that this "civilian science" was not really a civilian science, but a close exchange with astronomers at that time.

For example, the relationship between Zhou Shuxue and Xing Yunlu was extraordinary, and the relationship between Xing Yunlu and Wei Wenkui was both a teacher and a friend. It was naturally extraordinary that this line of inheritance was passed down.

In Wei Wenkui's narration, China discovered the "heliocentric theory" and there is also a context to follow.

For example, in the Sui Dynasty, people discovered that "the five stars are the masters of the five virtues. They move into the ecliptic or out of the ecliptic, just like the movement of the moon with yin and yang."

By the Song Dynasty, "all five latitudes follow the ecliptic path of the sun, but the moon travels in nine paths."

It can be seen that from people's discovery that the five stars move in the ecliptic, to the discovery that the moon and the five stars have different orbits, to the discovery that "the sun is the king and the moon is the queen of the signs", and finally to "all are pulled by the sun", they are almost the same.

This made Zhang Shun couldn't help but look at traditional Chinese astronomy with admiration.

For this reason, Zhang Shun couldn't help but force the "spirited" Wei Wenkui to stay for a few days, and then reluctantly let him go until the content of the discussion was no longer new.

As soon as Wei Wenkui left, the missionary Tang Ruowang, accompanied by Wang Zheng, hurried over.

It turned out that Long Huamin, the president of the Jesuits in China at this time, was not very proficient in scientific knowledge such as astronomy and mathematics, so he had to send Tang Ruowang to replace him.

"The earth is the center of the stars!" Tang Ruowang said after seeing the ceremony.

"The sun and the moon all revolve around it, and the five stars of metal, wood, water, fire, and earth all move around the sun, and they also move around the earth with the sun."

"Other stars all orbit the earth, making one revolution every twenty-four hours..."

"Wait, wait!" Zhang Shung was stunned as soon as he heard the beginning, and quickly interrupted Tang Ruowang's explanation.

"If I understand correctly, you are saying that the sun and moon orbit the earth, and the five stars of gold, wood, water, fire and earth orbit the sun?"

"Your Majesty is right!" Tang Ruowang nodded and replied.

"Although this may sound shocking, it is true!"

What a shocking ghost!

Zhang Shun originally thought that he was either explaining the geocentric theory or the heliocentric theory.

But he never expected that Tang Ruowang would come up with such a "wrong theory" for him. What kind of hypothesis was this?

However, as soon as Tang Ruowang's "wrong theory" came out, Zhang Shun immediately realized a problem.

Was what Wei Wenkui was talking about earlier the "heliocentric theory" or the Tycho system?

Because Zhang Shun had a preconceived idea and thought that this was the heliocentric theory.

However, after listening to Tang Ruowang's words, he suddenly realized that if the earth was still placed in the center, wouldn't it be the same astronomical model used in the Far West?

If both parties are heliocentric or geocentric, it can be said to be a coincidence.

However, by coincidence, both sides came up with the "Tycho System" almost at the same time, which makes people suspicious.

The things that are right and wrong are almost the same, so there is a high probability that one of them is the result of research, and the other is the result of plagiarism.

It’s hard to say who is plagiarizing whom!

Of course, according to Zhang Shun's "records" in his previous life, there were three astronomical theories in Western Europe during this era, one was the Ptolemaic system, the other was the Copernican system, and the third one was Tycho in between. system.

After Copernicus proposed the heliocentric theory, in addition to being opposed by the church, most astronomers in Europe at that time did not agree with it.

The main reason is that some calculations and observations by astronomers at that time were inconsistent with the Copernican system.

At this time, the astronomer Tycho synthesized the "advantages and disadvantages" of the Ptolemaic and Copernican systems and proposed a compromise Tycho system.

Of course, although this system is a bit strange, it was a big improvement compared to the traditional Ptolemaic system at that time. In some cases, it was even better than the Copernican system in explaining the results of observations and calculations by astronomers at that time.

Therefore, as soon as this theory came out, it immediately received support from many astronomers.

Not to mention Zhang Shun's previous records, let's say that in fact, in order to completely overpower the "Qintian Prison" and "Eastern Bureau", Tang Ruowang specifically selected the Tycho system as the starting point, which he believed had the most advantages.

"Okay, you continue!" Zhang Shun couldn't help but nodded after listening to Tang Ruowang's words, and was undecided for a while.

Now he was about to evaluate the level of astronomy development on both sides, so he focused on listening.

Sure enough, after Tang Ruowang explained the Tycho system vividly, he saw that Zhang Shun was unmoved and said that he "didn't know the stuff." So, he pulled out the Ptolemaic system and criticized it.

The so-called Ptolemaic system is naturally not a simple geocentric theory.

Rather, it is an astronomical system centered on a point outside the earth and fitting the trajectories of a large number of stars and planets around the area inside the earth.

Zhang Shun originally didn't care much about this, and was thinking about asking Wei Wenkui what the relationship between the earth and the sun was like.

Just as he was listening, he suddenly thought of a person Ge Chengke mentioned a few days ago.

This man is the famous martial artist and strategist Tang Shunzhi. In fact, he is also a famous astronomer.

This person is famous for his research on the "Arc Arrow Technique" and "Hijri Calendar" in the "Time-giving Calendar".

This "Hijri calendar" was originally introduced to China in the Yuan Dynasty. After the fall of the Yuan Dynasty, Zhu Yuanzhang ordered people to translate it into Chinese to supplement the shortcomings of the Chinese calendar.

However, because the legislative principle of this calendar is different from the traditional Chinese calendar, only a small number of algorithms have been absorbed, and its principles are not clear.

Until Tang Shunzhi, who likes to pursue the "li", discovered this while studying the "Hijri".

So, he calculated in reverse, "judged his chart" and drew a star chart.

Originally, he wasn't very interested in this messy star map, but when he saw the Ptolomy system map that Tang Ruowang brought, he couldn't help but be stunned.

It turns out that this picture is fifty or six points similar to the star map drawn by Tang Shunzhi.

Suddenly, an extremely bold guess appeared in his mind.

In fact, this Ptolemaic system was copied from the "Hijri", and the Tycho system was copied from the Zhouxuology model.

From this, we can infer that there must be a heavyweight in the Qintian Prison or the Eastern Bureau who advocates the so-called "Copernican System!"

Since then, the sources of the three so-called major systems in the West in my previous life have become clear!

The author originally did not want to write any pseudo-historical theory. He originally planned to write a story where Chinese and Western astronomy complement each other and let the protagonist lead China into the scientific era.

Unfortunately, when the author continued to check relevant information, he suddenly discovered a big problem. The emergence of a new astronomical model requires a step-by-step process.

In the Ming Dynasty, the emergence process of the "Tychonic System" was clear and clear. On the contrary, the Tychonic System and the Copernican System in the West seemed to pop out of a stone.

The author's findings coincided with Mei Wending's concepts in the late Ming and early Qing dynasties, so in the end the author rewrote this chapter and the final conclusion.
